Solution In Progress - Updated -

Issue

  • (polkitd, dbus-daemon, accounts-daemon) 每个都消耗了大约 10% 的内存资源,且正在持续增加。
    USER      PID    %CPU  %MEM  VSZ-MiB  RSS-MiB  TTY    STAT  START  TIME     COMMAND  
    polkitd   789    9.0   0.0   530      13       ?      Ssl   2018   8066:42  /usr/lib/polkit-1/polkitd --no-debug 
    dbus      772    7.3   0.0   61       4        ?      Ss    2018   6519:31  /usr/bin/dbus-daemon --system --address=systemd:

  • gnome-settings-daemon 插件在一个持续循环中轮询 accountsservice
  • 在升级到 RHEL 7.4/7.5/7.6 后,polkitdaccounts-daemon 似乎会消耗更多的 CPU 资源。

Environment

  • Red Hat Enterprise Linux 7.4/7.5/7.6
  • polkit-0.112-14.el7.x86_64
  • accountsservice-0.6.45-7.el7.x86_64
